Specification :

The 9820 and 9830 sensing probe monitors the capacitance field around the
active probe. As the volume of product increases in the vessel, the probe
capacitance changes. This change is used to activate the relay for a high or low
alarm. A two point calibration can be set to control a differential between two
points along the probe for pump or valve cycling.
• no moving parts
• remote electronics via standard twisted
pair with the 9830
• available with Intrinsic Safety Barrier for
Hazardous Locations on the 9830
• 9820 can be integral to the probe
• high corrosion resistant Teflon and
stainless steel wetted parts
• capacitance technology responds to all
product types
• HF capacitance technology does not
require routine cleaning
• easy calibration and control set-up
